I'll base my response on the assumption that the hospital has ruled out a brain tumor or other sever neurological disorders via imagery and diagnostic testing, if not, he needs to see a neurologist ASAP.

In Chinese medicine, as you have described it, I would suspect this sort of pain to be an aspect of severe "blood" stasis, where the 'blood" stasis is and its origin would require a proper evaluation. Other things to look for is fascial pain syndromes (myofascial dysfunction, trigger points) and the autonomic phenomena that can come with it, these conditions being western explanations of qi and "blood" stasis and can be be treated effectively by a well trained Chinese medical practitioner with the use of acupuncture, moxibustion, physical manipulation and therapy, and herbal medicine.

Good Luck!
